What to check when an AI service is down

When Claude or ChatGPT suddenly stops answering, this is what to look at and in which order: how to tell a provider outage from a problem on your side, and how to choose another service in the meantime. Only things we can back up are written here; where we cannot check something, we say so.

1. What this page is

Every AI company runs its own status page: Anthropic at status.claude.com, OpenAI at status.openai.com, Google on its Cloud and Workspace dashboards. When something breaks, that is where the company writes it first. The trouble is that they are scattered. If you use several tools you end up visiting three or four pages, and in between you wonder whether the problem is on your side.

This app gathers the data those official pages publish, once a minute, onto one screen, and lists the services that are operational as "Working right now". We measure nothing ourselves; we only relay what each company wrote on its own page. The official page is the source of truth and this screen is a window onto it.

2. What the status words mean

Providers use different vocabularies, so we fold them into five words. Here is the mapping.

GitHub Copilot is read from only the components whose name contains Copilot, not the whole GitHub page. The Gemini app and the Gemini API are two rows because Google reports them on two different dashboards.

3. What we check and what we cannot

These are the sources checked automatically. Every URL was verified to respond on 4 September 2026. The scope column is what the company itself says the page covers.

Some we cannot check: Grok (xAI), Mistral, DeepSeek, Hugging Face, Together AI, Midjourney publish no machine-readable data, so we only link to them. We do not guess their status.

The interval is 60 seconds: our server fetches once a minute and your screen reads that copy, so a change on a provider page can take up to a minute to show here. Alerts are browser notifications and arrive only while this tab is open. There is no server push, so closing the tab stops them. That is deliberate: it runs with no server cost and avoids an alert that looks like it works and then silently does not.

4. The order to check during an outage

  1. Look at that service's row. If it says outage or partial outage, it is the provider. The official page link shows which features are affected and whether a fix is under way. This settles most cases.
  2. If it is operational but fails only for you, read the error code. 429 means too many requests, usually your account's rate or quota limit (RFC 6585). 503 means the server is temporarily unavailable (RFC 9110). 529 is the code the Anthropic API returns when it is overloaded (overloaded_error). 401 and 403 are key or permission problems, not outages.
  3. Check the infrastructure rows. If Cloudflare, Vercel or Supabase show trouble, many services built on them wobble together. When several things break at once, suspect this first.
  4. Rule out your side. If other sites are slow too, it is your network. Corporate networks and VPNs sometimes block one service only. Browser extensions, ad blockers in particular, can break a chat page. Trying a private window or another device usually settles it.
  5. Wait a few minutes. For a provider outage there is nothing to do but wait until the incident on the official page moves to monitoring or resolved. With alerts on, you are told when it comes back too.
